Common Causes of Auto Electrical Problems

Posted on

Car problems can happen to anyone at any given time. Knowing a little about the possible causes of electrical problems can help save time and money in resolving the problem. Here are some common electrical problems that may occur in your vehicle and their prospective causes.

Dead Battery

Your car could refuse to start due to a dead or weak battery. You may have left your headlights on accidentally when going shopping or having dinner out with your friends, causing the battery to be drained of power. Jump starting your vehicle can often remedy this problem. Car batteries can also malfunction due to faulty components or old age, requiring that you invest in a new one to keep your car functioning at its best.

Alternator Problems

Your car’s alternator recharges the battery as your vehicle is running. A broken connection with the alternator can result in your battery becoming drained of power. Your battery can also suffer if the alternator belt cracks or wears out. By having these parts checked regularly, you can help avoid battery problems that put you and your vehicle out of action.

Spark Plugs

Spark plugs and their respective wiring are essential electrical components in your vehicle. Bad plugs or wires can cause the engine to malfunction, resulting in rough idling, slow acceleration, stalling and poor mileage. You can avoid these problems by changing old and worn spark plugs or fixing faulty wiring during your regular car tune ups.


Broken electrical wires and blown fuses can also cause electrical problems in your vehicle. Your vehicle’s electrical components all tie into your electrical system through wiring which corresponds to a specific fuse. Fuses are designed to protect your vehicle’s sensitive circuits from suffering damage due to power surges or overloads. Blown fuses prevent electricity from reaching your brake lights, dash, horn and other electrical gadgets. Before investing in expensive parts for repairs, check your fuses to see if they are the cause of the problem.


Solenoids are magnetic coils that distribute power to your vehicle’s starter and its automatic door locking system. A faulty solenoid can have the same effect as a dead starter or battery. Regular car maintenance and care can identify worn or damaged solenoids in time to prevent startup problems.

Even with regular auto maintenance, electrical difficulties may arise. It helps to know a trustworthy auto electrician in Southport for immediate servicing when you need it most. Knowing a qualified auto electrician could help you get back on the road in no time.
